I put a '37 GMC T-18HD truck and original frame on axles with power steering gear from '95 GMC P3500 HD axles, made all new suspension with longer, more flexible, parallel front springs and air in rear for comfortable ride. '95 vehicle had 19.5 wheels with 5/10 bolt pattern so I was able to mount 22.5 wheels and tires. This size truck has enough engine compartment length for a 6bt or a DD 4-53T, both about the same length, used the Detroit.

I have another Dodge Cumming 4wd frame and running gear for another project, but with 8 bolt wheels, so will have to use another wheel/tire combination.
